* arch: arm: cxd56xx: Add irq routing for SMP in cxd56_irq.c
NOTE: In cxd56xx, each external interrupt controller can be
accessed from a local APP_DSP (Cortex-M4F) only. This commit
supports IRQ routing for SMP by calling up_send_irqreq() in
both up_enable_irq() and up_disable_irq().

======
|
||
|
||
Spresense is a compact development board based on Sony’s power-efficient
|
||
multicore microcontroller CXD5602. It allows developers to create IoT
|
||
applications in a very short time and is supported by the Arduino IDE as well
|
||
as the more advanced NuttX based SDK.
|
||
|
||
- Integrated GPS
|
||
The embedded GNSS with support for GPS, QZSS and GLONASS enables applications
|
||
where tracking is required.
|
||
- Hi-res audio output and multi mic inputs
|
||
Advanced 192kHz/24 bit audio codec and amplifier for audio output, and
|
||
support for up to 8 mic input channels.
|
||
- Multicore microcontroller
|
||
Spresense is powered by Sony's CXD5602 microcontroller (ARM® Cortex®-M4F × 6
|
||
cores), with a clock speed of 156 MHz.
|
||
|
||

|
||

Configuration sub-directories
|
||
-----------------------------
|
||
|
||
smp
|
||
|
||
This is a configuration to run Spresense in SMP mode. To use this
|
||
configuration, new boot loader which will be released later must be used.
|
||
|
||
wifi
|
||
|
||
This is a configuration for Spresense + Wi-Fi addon (Telit GS2200M) module.
|
||
With this configuration, (1) you can connect Spresense to an existing Wi-Fi
|
||
access point (2.4GHz 802.11b/g/n are supported) or (2) you can make
|
||
Spresense as a Wi-Fi access point. In both cases, you can login to the
|
||
Spresense with telnet, also access to a webserver (NOTE: this case you need
|
||
an extension board with microSDHC card)
|
||
|
||
(1) Station (STA) mode
|
||
|
||
To run the module in Station mode (i.e. to connect to an existing Wi-Fi
|
||
access point), You need to specify SSID with passcode.
|
||
|
||
nsh> gs2200m ssid-to-connect passcode &
|
||
|
||
If the connection succeeded, IP address is statically assigned.
|
||
|
||
nsh> ifconfig
|
||
eth0 Link encap:Ethernet HWaddr 3c:95:09:00:69:92 at UP
|
||
inet addr:10.0.0.2 DRaddr:10.0.0.1 Mask:255.255.255.0
|
||
|
||
Then, you can run DHCP client (renew command) to obtain IP address as well
|
||
as DNS server information. (NOTE: In current configuration, DHCP client on
|
||
GS2200M is disabled. If you enable the internal DHCP client, you can not
|
||
use DNS client on NuttX)
|
||
|
||
nsh> renew eth0 &
|
||
renew [6:100]
|
||
nsh> ifconfig
|
||
eth0 Link encap:Ethernet HWaddr 3c:95:09:00:69:92 at UP
|
||
inet addr:192.168.1.101 DRaddr:192.168.1.1 Mask:255.255.255.0
|
||
|
||
Now, you can run telnetd and webserver on Spresense.
|
||
|
||
nsh> telnetd &
|
||
telnetd [7:100]
|
||
nsh> webserver &
|
||
webserver [9:100]
|
||
nsh> Starting webserver
|
||
|
||
Also, you can run NTP client to adjust the RTC on Spresense. (NOTE: we
|
||
assume your network can access to pool.ntp.org, otherwise, you can specify
|
||
CONFIG_NETUTILS_NTPCLIENT_SERVER)
|
||
|
||
nsh> date
|
||
Jan 01 00:00:36 1970
|
||
nsh> ntpcstart
|
||
Started the NTP daemon as PID=11
|
||
nsh> date
|
||
Jul 30 06:42:13 2019
|
||
|
||
(2) Acess Point (AP) mode
|
||
|
||
To run the module in AP mode, you need to specify SSID to advertise and
|
||
WEP-key. (NOTE: in AP mode, you can also specify channel number to use)
|
||
|
||
nsh> gs2200m -a ssid-to-advertise 10-hex-digits-wep-key &
|
||
|
||
If the module was initialized in AP mode, you can see a new IP address is
|
||
assigned.
|
||
|
||
nsh> ifconfig
|
||
eth0 Link encap:Ethernet HWaddr 3c:95:09:00:69:93 at UP
|
||
inet addr:192.168.11.1 DRaddr:192.168.11.1 Mask:255.255.255.0
|
||
|
||
Now you can connect your PC to the AP with the above SSID and WEP-key
|
||
which you specified.
